.SH "NAME"
mariadb-tzinfo-to-sql \- load the time zone tables (mariadb-tzinfo-to-sql is now a symlink to mariadb-tzinfo-to-sql)
.SH "SYNOPSIS"

.SH "DESCRIPTION"
.PP
The
\fBmariadb-tzinfo-to-sql\fR
program loads the time zone tables in the
mysql
database\&. It is used on systems that have a
zoneinfo
database (the set of files describing time zones)\&. Examples of such systems are Linux, FreeBSD, Solaris, and Mac OS X\&. One likely location for these files is the
/usr/share/zoneinfo
directory (/usr/share/lib/zoneinfo
on Solaris)\&.
.PP
\fBmariadb-tzinfo-to-sql\fR
can be invoked several ways:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmariadb-tzinfo-to-sql \fR\fB\fItz_dir\fR\fR
shell> \fBmariadb-tzinfo-to-sql \fR\fB\fItz_file tz_name\fR\fR
shell> \fBmariadb-tzinfo-to-sql \-\-leap \fR\fB\fItz_file\fR\fR
shell> \fBmariadb-tzinfo-to-sql \-\-skip\-write\-binlog \fR\fB\fItz_dir\fR\fR
.fi
.if n \{\
.RE
.\}
.PP
For the first invocation syntax, pass the zoneinfo directory path name to
\fBmariadb-tzinfo-to-sql\fR
and send the output into the
\fBmariadb\fR
program\&. For example:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmariadb-tzinfo-to-sql /usr/share/zoneinfo | mariadb \-u root mysql\fR
.fi
.if n \{\
.RE
.\}
.PP
\fBmariadb-tzinfo-to-sql\fR
reads your system's time zone files and generates SQL statements from them\&.
\fBmariadb\fR
processes those statements to load the time zone tables\&.
.PP
The second syntax causes
\fBmariadb-tzinfo-to-sql\fR
to load a single time zone file
\fItz_file\fR
that corresponds to a time zone name
\fItz_name\fR:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmariadb-tzinfo-to-sql \fR\fB\fItz_file\fR\fR\fB \fR\fB\fItz_name\fR\fR\fB | mariadb \-u root mysql\fR
.fi
.if n \{\
.RE
.\}
.PP
If your time zone needs to account for leap seconds, invoke
\fBmariadb-tzinfo-to-sql\fR
using the third syntax, which initializes the leap second information\&.
\fItz_file\fR
is the name of your time zone file:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmariadb-tzinfo-to-sql \-\-leap \fR\fB\fItz_file\fR\fR\fB | mariadb \-u root mysql\fR
.fi
.if n \{\
.RE
.\}
.PP
Using the \-\-skip\-write\-binlog option prevents writing of changes to the binary log or to other Galera
cluster members. This can be used with any form of running \fBmariadb-tzinfo-to-sql\fR.
.PP
After running
\fBmariadb-tzinfo-to-sql\fR, it is best to restart the server so that it does not continue to use any previously cached time zone data\&.
